Piezoelectric Active Vibration Control of Large Membrane Diffraction Space Telescope
With the development of aerospace technology,large membrane diffraction space telescopes have gained widespread attention and research due to their advantages such as small mass and volume,high optical imaging capability,and ease of folding and unfolding.In this paper,we conduct vibration control research on a large membrane diffraction space telescope and provide a vibration control strategy based on piezoelectric actuators.Firstly,the finite element method is used to establish the dynamic model of the structure.Then,the position of the actuator is studied based on the controllability criterion.The control law is designed based on the fuzzy proportional-derivative(PD)algorithm.Finally,the effectiveness of the proposed method in this paper is verified through numerical simulation.In this paper,the corresponding relationship between the number of piezoelectric actuators and the stability time is studied through numerical simulation,and the robustness of the control law is also investigated.
